The core of this book is the life story of a manuscript codex, British Library Royal MS 13 E IV: the Latin Chronicle (from the Creation to 1300) of Guillaume de Nangis, copied in the abbey library of St-Denis-en-France. The authors shed new light on the production process, identifying the illuminator of the Royal MS and naming the scribe. Detailed evidence links the codex to important events in history, such as the Council of Constance, and famous actors like Jean de France, duc de Berry, Sigismund of Luxembourg, Thomas Howard, duke of Norfolk, and Henry VIII, to name a few. The authors show how it traveled from one capital to the other, narrating the entire life and interesting times of this codex. Another dimension of this study accounts for all twenty-two copies of the Chronicle, now scattered in nine cities from London to Vienna, placing each one in a scrupulously drawn stemma codicum and sketching its history.
